When electricity returns but the opener does not respond, note whether other garage equipment has power and which controls still work. Avoid assuming that the motor burned out. Do not operate a door that also shows storm or impact damage.

Distinguish local control from app access
Tell us whether the wall button, remote or app has the problem. A restored household supply does not establish that every device and network connection has recovered. Record any indication already visible, without opening the unit or repeating a failed movement.
Arrange access without forcing the door
If a vehicle is trapped or the garage is your only entrance, say so when calling. Do not release or lift a damaged or unstable door. An appointment can address the diagnosed fault and discuss whether compatible battery backup would help with future outages; backup is not a repair for an existing mechanical problem.
Frequently Asked Questions
Will replacing a backup battery fix every outage-related fault?
No. The battery, main power path, control system and mechanical door are separate possibilities to assess.
Should I erase all remote settings after an outage?
Not automatically. Preserve the existing setup until the symptom and correct model-specific procedure are understood.
